you are getting worse and worse. the match one was somewhat better as it dealt with actual travel of AIR instead of a liquid.
The issue is you don't need to be able to blow out a candle at 16" to give someone else Covid. thats typically NOT how airborne transmission is worried about. The real concern is the "linger" factor. I know you aren't listening to an actual medical professional so I am sure you won't listen to a different type of professional, but pre-2020 the code for hospital air systems was to keep air moving to cut down on airborne transmission. Lots of fresh air, lots of air movement. slower/stagnant air is a better environment to keep most air borne diseases alive outside the body, which makes sense because they want to live in your lungs where its nice and warm. basically it was better to have a more "dense" exposure that went away quickly than it is to have less "dense" exposure that stuck around for a while.
the better analogy would be to wear a mask while walking through a smokey area. the smoke is the covid/airborne diseases. the mask doesn't stop you breathing it in, or someone else breathing it out. It may limit the initial spread distance, but the lingering part is the issue.
for what its worth, the code for hospital air quality hasn't really changed since 2020, except to include more UV lights/better filters which only helps with the linger factor, and not the initial spread.
